Hollow-jet valves

For environment friendly discharge

In hydropower plants, irrigation dams, compensating reservoirs or detention reservoirs, hollow jet valves are used for environment friendly discharge of water downstream or into a tailwater pool while simultaneously enriching the water with oxygen. The hollow jet valves made from high quality steel in combination with a elastic/metal seal and integrated jet deflector facilitate cavitation- and vibration- free energy dissipation. Electric and hydraulic operation allow excellent control performance. Electric heaters for use in cold climates and other specific customer requirements can be implemented. The control system can be designed such that the control room can recognise the cylinder‘s position at all times. This allows a precise control of the discharge volume.
